Embodiment 1

[0059] (1) First cut the foamed nickel (110ppi foamed nickel) into a rectangle (0.690 g) of 4*6*0.05 cm, the width is similar to the inner diameter of the reactor, and the length is flush with the page, so that the foamed nickel remains upright during the reaction , which is conducive to a more uniform reaction. Then put the cut nickel foam into a 200mL beaker, pour 100mL of acetone into it and sonicate for 30min with a power of 240w. Then pour off the acetone, rinse with deionized water, and then pour 100mL of absolute ethanol into the same ultrasonic wave for 30min (power 240w). Finally, the absolute ethanol was poured out, rinsed with deionized water, and then ultrasonicated with deionized water for 30 minutes (power 240w). After the ultrasonication is completed, the treated foamed nickel is vertically placed in a 150mL autoclave.

Then put the cut nickel foam into a 200mL beaker, pour 100mL of acetone into it and sonicate for 40min with a power of 200w. Then pour out the acetone, rinse with deionized water, and then pour 100mL of absolute ethanol into the same sonication for 40min (power 200w). Finally, the absolute ethanol was poured out, rinsed with deionized water, and then ultrasonicated with deionized water for 40 minutes (power 200w). After the ultrasonication is completed, the treated foamed nickel is vertically placed in a 150mL autoclave.

Embodiment 3

[0073] (1) First cut the foamed nickel (110ppi foamed nickel) into a rectangle (0.690 g) of 4*6*0.05 cm, the width is similar to the inner diameter of the reactor, and the length is flush with the page, so that the foamed nickel remains upright during the reaction , which is conducive to a more uniform reaction. Then put the cut nickel foam into a 200mL beaker, pour 100mL of acetone into it and sonicate for 50min with a power of 180w. Then pour off the acetone, rinse with deionized water, and then pour 100mL of absolute ethanol into the same sonication for 50min (ultrasonic power is 180w). Finally, deionized ethanol was poured out, rinsed with deionized water, and then ultrasonicated with deionized water for 50 min (ultrasonic power: 180w). After the ultrasonication is completed, the treated foamed nickel is vertically placed in a 150mL autoclave.

Abstract

The invention discloses a water treatment nickel-based self-growing three-dimensional material and a preparation method thereof. The method includes the steps: (1) cleaning a metal substrate by surface treating agents to obtain a metal substrate I; (2) dissolving nickel salt and ferrous iron salt in solvents, adding precipitating agents and protective agents and uniformly stirring materials to obtain mixed solution; (3) pouring the mixed solution obtained in the step (2) into the metal substrate I obtained in the step (1), performing reaction under the condition of 110-130 DEG C, and then washing and drying precipitates to obtain a nickel ferrite / foam nickel composite precursor material; (4) calcining the nickel ferrite / foam nickel composite precursor material obtained in the step (3) to obtain the water treatment nickel-based self-growing three-dimensional material. The method is simple, easy, low in cost, green and environmentally friendly. The prepared nickel-based self-growing three-dimensional material is large in specific surface area, and organic dyestuff and heavy metal ions in sewage can be effectively removed.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment, in particular to a nickel-based self-growing three-dimensional material for water treatment and a preparation method thereof. Background technique [0002] In recent years, with the acceleration of industrialization, environmental pollution has become a serious threat to human production and life and health. Among them, the water pollution problem has attracted more and more people's attention, and has become the key to the pollution problem. Toxic heavy metal ions and organic dyes are generally not prone to photodegradation and biodegradation, and they tend to accumulate in tissues and cause serious bodily harm. Therefore, the removal of heavy metal ions and organic dyes from wastewater has become an important means to deal with environmental pollution. [0003] So far, many methods for eliminating water pollutants have been developed, such as adsorption, flocculation, ozonation, memb...
